Yes, it is even more mild than the stock slider cams.

The RR is basically a stock replacement as far as specs go. We have a 3 gas IM240 type roller dyno / drive cycle test here, and my TC with RR (and a bunch of other mods) always passes with flying colors. Emissions are so low, they dont even need to complete the complete 4 min drive cycle test.
